Nvidia demoed Kepler...running real time ray tracing around this time last year. Given the fact that GG (Guerilla Games) is using this inside their new engines, would have us believe that ps4 is atleast on par with Kepler based chipset.

In the PC world, Devs couldn't take advantage of this because their minimum requirements wouldn't be able to take advantage of this. But now that the Ps4 can support this, you can guarantee will be seeing this in most games in the future. In other words, new consoles allow for PC devs to raise the minimum bar for PC.

This is why i don't get why PC guys are up in arms. PC ,subsequently through ports or being lead platform, get more games supporting more of these features. This is because multiplatform titles. Author notes that their are currently no games on PC taking advantage of this feature.

"Nvidia demoed Kepler... running real time ray tracing around this time last year"

That's why, perhaps. PC guys are pretty riled up since there's a lot of tech in their expensive cards but no one's using them. They have to wait for the consoles to catch up before any of the unused features are utilized. Now comes a game that will be one of the first to use one of the tech already available on the PC and it's a console exclusive launch title. At the same time console gamers told PC guys to wait for the ports.

DX11 was laughed off as a joke just a couple of years ago since you can count with your fingers the amount of games that use it. GDDR5 has become a standard in PC gaming and yet no one cared to bring it to any discussions before. And any other tech that were demoed when nvidia and AMD were selling their new cards.

Now console guys are chattering about those features like it's the Second Coming while the PC guys stood at the dark corner....muttering they saw those features first.

You have to keep something in mind though, Warhawk used raytracing to render the volumetric clouds, and that was a PS3 launch title (that got delayed a bit). Just because you use raytracing on one aspect of your game does not mean your hardware supports real time raytracing of an entire scene. Even our best GPUs don't do a very good job at that at this point. We still have to cut corners and fake things that would be raytraced entirely on a CGI pre-rendered scene.

PC always takes advantage of this last as its developers usually aim for a wide spread of specs. New consoles are a plus and provide a leap even to PC games. Well the multiplatform ones. There will be substantial change over the next year for PC games. As many will adapt to OpenCL/OpenRL and so on to mix into DirectX/OpenGL. For a more GPGPU like development process. Sounds complex, but its really not to a seasoned developer. Even WiiU could benefit if PC developers adopt to this as they would likely start in the low range of it. Just right for WiiU ports.

Only thing this tech demo does to me is confirm OpenRL or some type of custom OpenRL extensions are supported on PS4.

I understand that PC guys are frustrated. But they shouldn't be frustrated at consoles or console gamers (or gamers that game on pc and console). Some people just don't want to keep up a gaming pc.

Maybe PC gamers (who buy latest pc hardware), should be upset at companies like nvidia a) who make the hardware so expensive and keeps the market niche b) doesn't invest in developers to take advantage of their new tech

Maybe PC gamers should be upset at Microsoft a) who do not provide a game friendly OS b) who competes with it self (pc gaming on windows) with xbox and releases games exclusive to their xbox os vs. windows os. Why couldn't microsoft's E3 presence mean announcing PC games and support?

Or maybe PC gamers (who buy latest tech hardware) should accept that they are a part of a niche market and be done with all this complaining... so gamers can enjoy talking about games.

"That's why, perhaps. PC guys are pretty riled up since there's a lot of tech in their expensive cards but no one's using them. They have to wait for the consoles to catch up "

i'd dispute that notion . It always seemed to me that PC has always been schizophrenic that way ... without the influence of the current era consoles .

I remember a time when consoles developpement wasnt a priority for most pc game publishers and still they were holding back , besides the occasional graphical juggernauts , especially in fps , because of lew entry - mid range pcs .

The definition of ray-tracing is kinda vague. Some tech demos do complete raytracing, which is extremely expensive but looks cool; and games now are starting to use some optimized, semi-ray tracing in which they trace light only from certain places to certain endpoints.

Killzone is my favorite FPS and I'm SURE people that bashing this game just play a little or nothing both MP and single.

Talking about Kz3, the multy is incredible well done and every time I jump in a match I'm still amazed by the incredible quality of the graphics (both art and features). Probably Kz3 have the most advanced graphics on this gen (Ps3 and X360), a solid 30fps and a tons of graphics effect in the scene.

No doubt Kz3 is the most underrated FPS of this gen and I really hope the next Killzone on PS4 will deliver the same experience and will open the eyes to everybody.

I think personally KILLZONE has undergone an evolution with every title released. I am disappointed a little with MP, but I just like open battlefield like maps or bigger maps. Its the type of game I am into the most. Its still great.

Shadow Fall will definitely be a great title. E3 will amaze all when it lands there.

I agree with the first sentence :) Killzone 3 is weak in terms of content compared to the extremely impressive Killzone 2 which had best online best single player of the two.

KZ3 might be better technically but KZ2 overtakes it in terms of fun and multiplayer. Very few are playing KZ3 right now online and the fact i cannot join a custom game, the terrible spawn system and the very limited unlock system compared to KZ2 killed it for me.

Killzone 3 is far and away the best looking multiplayer game on console this generation, anyone contending that need to get thier eyes checked. That and the fact that it ran silky smooth at 30fps made it not need 60 fps. Absolutely stellar gameplay.

And they, the nobady said "PS4 is not high end" I lol they say " C3 looks as good as KZSF" a actual current gen port and I lol they can't see the amazing visuals.. for any human is obvious that KZSF looks like a new gen.. way ahead anything in todays pc.

first game using raytracing boom! Pc nazis cry in a lil empty corner..

Ok ok PC games will start having this amazing tech to soon.. be happy love.smile.play

KZSF will be the best launch title ever! It will beat RFOM .. I can tell. People.. give love to KILLZONE! it deserve it... it just does.. is a game that is not perfect but keep improving and try to please the fans and the media.. amazing gameplay and amazing visuals.. and this one will have a amazing campaign .. they try it with kz3 they hire professional writers and all that.. they always listen to every complain and try to do better.

they say no pc game does such a thing ... and know Crysis 3 does? Show me prove.. and you. I see all pc gamers crying saying this is possible in todays PC but frame rate will suffer big time even on A high end pc, the fact is that no game does it.. I cold talk bs and say well ps3 games can do 4k.. see how stupid I sound?

Oh weit you are talking about reflection lol Well KIllzone:sf will have raytrace something no pc game has done jet. Many games do reflections but not real time raytrace.

Thanks for hating .. but by your answer you can't have a argument with me.. first learn how to read and be informed.

Real time Raytraycing is been used in KZSF and is the first game doing it.. it's a fact.

Real TimeRay-tracing being used in Killzone:SF. Given the fact that the was achieved with (at the most)3gb or GDDR5, I'm sure the game will only look better with the 8gb GDDR5.

Now I'm not saying the extra RAM creates better graphics. But this will allow Guerilla Games to push the GPU even further while being able to maintain that 30FPS. So while the naysayers say that Killzone:SF won't look much better than the demo last February. I'd hold out on the predictions until we see final code.

The fact that this is using ray-tracing @1080p, while being only a launch title shows what we're in store for next gen.

@Gunnerforlife,Even then that's just a guess in my opinion. We don't know how much is actually set aside for the OS; probably a 1gb. This is also assuming the Guerilla had the very latest devkit available.

On a side note, people never thought ray-tracing was possible in games 5 years ago. Technology has came a long way since then. People thinking that ray-tracing now isn't possible need to watch Nvidia's Kepler demonstration. Developers can now achieve this, now everyone's focusing on SVOI (Global Illumination).

It was suggested in an interview that the OS actually has a separate pool of memory. So potentially, the devs could have the entire 8 GB. Though, I think they would still be happy with 7 GB.

I'm too lazy to look for it, so you'll just have to take my word for it. Or don't, I don't care. But it was suggested it was done that way to accommodate streaming and sharing while playing without eating at gaming resources.

I share the same excitement as you do with the PS4 and its potential capabilities.

Does anyone know whether the 8 GB GDDR5 includes whatever amount the GPU has as well? Or does the GPU has it's own dedicated VRAM that can also tap into the unified 8 GB GDDR5?

I would like to know more about the GPU. Hopefully we would find our more about the PS4 in general soon, as I find myself visiting N4G on a daily basis now and clicking on the PS4 tab at the top for recent news on it.

i remember just a few weeks back a pc owner comment(Cant remember specific name) in these very pages of n4g saying the ps4 has no chance of real time ray tracing , even a high end pc would struggle. Time to eat your words non believers.

That is awesome! I was wondering how come no one made any Mark Cerny .gifs considering how important he is now to the PS4.

I look forward to more awesomely funny gifs of Mark Cerny. When he talks, you can tell he is so passionate in what he does. With all those expressive expressions, I can tell there would be some really funny ones to come.

Real interesting stuff. I'm curious how GG is going to take advantage of this real time ray tracing. You could already see some of it in the demo when the Shadow Marshall went down the stairs with the metal wall in the destroyed building.

Well this is awesome, but Im sure I read that Polyphony Digital was using ray tracing In limited capacity on Gran Turismo 5. Here's the link. http://www.ign.com/articles...

It's nice to see that Ray Tracing is being fully utilized in game. Deffered Rendering and MSAA were features only used on High end PCs a few years ago and Both Killzone 2 and Saboteur and God of War 3 were able to capitalize on this features extensively on PS3, Ray Tracing was barely possible on PS3 let alone Xbox 360 and One game managed to pull it off though limited. I'm glad Next Gen Games on consoles are using this now...

I haven't heard of any game on the PC since 2010 with all its power utilize Ray Tracing, once again, console devs are pushing the innovation forward with features PCs have had but NEVER use.

"the clouds are most likely using simple raycasting, ie. rays are not bounced around and traced into the scene, so it is nowhere near as demanding as using raytraced reflections, refractions, or global illumination"
